Professor hohn has an insurance policy on her car with a $500 deductible. this means that if she gets into an accident she will personally pay for 100% of the repairs up to $500, with the insurance company paying the rest.
suppose the the cost of repairs for the next accident is uniformly distributed between $100 and $1500. let x denote the amount professor hohn will have to pay.
(a) find the cumulative distribution function of x.
(b) compute the expected value of x.

x+3=-10

-10+3=-7

x=-7

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
